Problems solved by technology

[0003] The shape of the brazing clip involved in this design is irregular, and the blanks are mostly forgings or precision castings. There are short cylinders and end faces on both sides that need to be processed. Because the short cylinders are relatively short, and the center of mass of the parts deviates more from the center of the short cylinders, direct clamping It is not safe, and if direct clamping is used for turning, the position error of the blank cannot be eliminated

Embodiment 1

[0036] yT23 rock drill is a high-efficiency air-leg rock drill, which is mainly used for rock drilling in mining roadway excavation, and is also an important tool in railway, water conservancy construction and national defense stonework engineering. , can drill horizontal and inclined blastholes.

[0037] like Figure 7 As shown in the figure, the shape of the drill card 300 involved in this design is irregular, wherein the left processing surface 310, the right processing surface 320, the back surface 330, the end surface 340, the arc groove 350 and the arc surface 360, the blanks are mostly forgings or precision castings , There are short cylinders and end faces on both sides that need to be processed. Because the short cylinder is relatively short, and the center of mass of the part is offset from the center of the short cylinder, direct clamping is not safe, and if direct clamping and turning are used, the position error of the blank cannot be eliminate.

Abstract

The invention discloses a tooling for drill truck cutting of a rock drilling machine, which comprises a clamp body and a rotatable clamping part detachably installed on the clamp body, and the drill clip is fixed on the rotatable clamping part; the rotatable clamping part includes a rotating A support frame, a positioning plate, a floating positioning column assembly, a pressing mechanism, a rotating shaft and a movable push pin assembly, and the clamp body includes a flange plate and a support frame vertically arranged on one side plane of the flange plate. Advantages, the tooling used for cutting the drill truck of the rock drilling machine uses the rotatable clamping part to drive the overall rotation of the drill card, and respectively cuts the surfaces to be processed on both sides of the drill card, without using two sets of tooling, and also avoids the use of blank surfaces. The inaccuracy caused by repeated clamping and positioning ensures the machining accuracy and improves the production efficiency.

Description

technical field [0001] The invention relates to a cutting tool for a rock drill, and belongs to the technical field of technological equipment for machining. Background technique [0002] yT23 rock drill is a high-efficiency air-leg rock drill, which is mainly used for rock drilling in mining roadway excavation, and is also an important tool in railway, water conservancy construction and national defense stonework engineering. , can drill horizontal and inclined blastholes. [0003] The shape of the drill card involved in this design is irregular, and the blanks are mostly forgings or precision castings. There are short cylinders and end faces on both sides that need to be processed. Because the short cylinders are relatively short, and the center of mass of the parts is offset from the center of the short cylinders, it is directly clamped. It is not very safe, and if direct clamping is used, the position error of the blank cannot be eliminated. For this purpose, special t...
